I apologize if this has already been covered -- I've read a lot of posts about the 2-4-1 offers, as well as the very helpful Tripadvisor article, and am still having trouble wrapping my brain around all the twists and turns and quirks.
My family will be in London in August for 7 nights. The 7-day travel card seems like our best option. We won't be taking public transport from the airport. We are staying near the St. James tube station in Westminster. There are only 3 attractions on the 2-4-1 offers that would work for us: St. Paul's, Churchill War Rooms, and Hampton Court. (Tower of London is not valid in August and I don't see Westminster Abbey listed at all.) We expect to use the Tube a lot. The only trains we will be taking are to Hampton Court and Watford Junction, but I think these are operated by South West and London Midland, not National Rail, so those journeys won't help us for the 2-4-1's, right? Here are my questions:
Is there is a difference in cost between a 7-day travel card purchased at a tube station vs. a 7-day paper travel card purchased at a rail station?
If I get paper travel cards at a rail station with the passport pictures, do these "scan" at the Tube turnstiles? Or do I have to get an attendant to open the gates every time as with the paper tickets (so the system won't "eat" the travel card)?
Is there a rail station in the Westminster area that sells the paper 7-day travel cards that is operated by National Rail (and therefore can sell me a travel card that will work for the 2-4-1)?
My husband is arriving a couple days later than the rest of us - can I buy him a paper 7-day travel card at the rail station if I have his passport size photo, or does he need to actually be there when it's purchased?
If I'm using the 2-4-1 vouchers, does that mean I have to wait in a long queue to buy tickets? I was planning on prebuying online to skip the ticket lines. Or do St. Paul's, Hampton Court, and Churchill War Rooms generally not have long lines in August?
And a related, probably stupid, question: do I actually buy the tickets and vouchers online on the DaysOut website (it says "add to cart,") or do I just register, print them, and show the voucher when I buy the tickets at the location?
Thanks SO much for your answers and patience.
